Discussion of Related Art

Generally, the door trim, which is internal of a vehicle door, providesa pleasant internal space and protects the components. and can becoupled to the inside of the door internal panel.

Conventionally, the door trim can be coupled to the door internal panelusing a fastener. Specifically, the fastener was mounted on the doortrim, and such a fastener was inserted into the insertion hole providedin the door internal panel, so that the door trim may be coupled to thedoor internal panel. A physical load had to be applied to insert thefastener into the insertion hole, and the fastener was shrink-fittedinto the insertion hole by the physical load.

According to the above-described conventional structure, the insertionforce required to insert the fastener into the insertion hole is large,and the assemblability is poor.

Further, to detach the door trim from the door internal panel, thefastener that had been shrink-fitted into the insertion hole had to bepulled out from the insertion hole by physical load. The physical load,that is, the detachment force, is much greater than the insertion force,and the detachability is very poor.

In addition, during the detachment of the door trim, deformation of thefastener and the door internal panel occurs, which necessitatesreplacement of the fastener or rework of the internal panel.
